Abstract

|
A non-motile, pink-pigmented bacterial strain designated IMCC25679T, was isolated from freshwater Lake Chungju of Korea. Phylogenetic trees based on 16S rRNA gene sequences showed that the strain IMCC25679T formed a lineage within the genus Pedobacter. The strain IMCC25679T was closely related to Pedobacter daechungensis Dae 13T (96.4% sequence similarity), Pedobacter rivuli HME8457T (95.3%) and Pedobacter lentus DS-40T (94.3%). The major fatty acids of IMCC- 25679T were iso-C15:0, iso-C16:0 and summed feature 3 (comprising C16:1ω6c and/or C16:1ω7c). The major respiratory quinone was MK-7. The major polar lipids were phosphatidylethanolamine (PE), an unidentified sphingolipid (SL), an unidentified aminolipid (AL) and three unidentified polar lipids (PL). The DNA G + C content of IMCC25679T was 32.2 mol%. Based on the evidence presented in this study, the strain IMCC25679T represents a novel species within the genus Pedobacter, with the proposed name Pedobacter aquicola, sp. nov. The type strain is IMCC25679T (= KACC 19486T = NBRC113131T).
